摘要：

Song variation was studied in Gambel's White-crowned Sparrows (Zonotrichia leucophrys gambelii), breeding in tundra and boreal forest habitats near Churchill, Manitoba. No significant differences were found among habitats in song characteristics of Z. l. gambelii. Songs of Churchill birds had the same sequence of elements (i.e., whistle, warble, buzz, and trill) as Alaskan populations, with some variations in element form. The absence of dialects in migratory populations of White-crowned Sparrows supports predictions of the Ranging Hypothesis.
